Abstract

Based on our spectrophotometric observations, we have studied the envelope of the HeN Nova Mon 2012. The abundances of some chemical elements in the envelope and its mass have been estimated. Our results show that the helium, nitrogen, oxygen, and neon abundances in the Nova envelope exceed the solar ones by a factor of 1.5, 33, 9, and 95, respectively. The envelope mass has been found to be 2.3 × 10−4M⊙.
